My brother has wanted to be able to hook up his laptop to his TV at college, but has been unable to since the laptop only has an s-video port, but the TV only has composite video.
So this summer break, he finally decides to break down and buy a s-video to composite video conversion cable. This brings me to the real problem.
The laptop won't output a video signal through the adapter. If you push the switch display button with the adapter cable attached, there will be a brief flash on the TV, but no picture will come up. Furthermore, if you hold the function key to see a list of available video modes, it only lists the computer's LCD panel.
For reference, the adapter he bought is this one:http://www.microcenter.com/single_product_...duct_id=0203647
The adapter itself works, as we tested it with an original Xbox with s-video output. The s-video port on my brother's laptop works, as it will output through a regular s-video port just fine. We also tested the adapter with another computer to make sure it wasn't something confined to my brothers laptop, but it didn't work with that computer either. Both computers are similar models and are running Windows Vista, if that helps. Also, the actual composite video plug on the TV works fine, since my brother has been playing game consoles on it ever since he got it.
I've tried looking online for a solution, but the only thing close to an answer I got was too vague to be helpful.
